Description

Technical Field

[0001] This utility model relates to agricultural harvesting machinery, specifically a conveyor for laterally transporting the top ears of tall crops in a harvesting device for the top ears of crops. Background Technology

[0002] Tall crops, such as sorghum and sugarcane, present challenges in harvesting the top ears or shoots due to their overall height. In existing harvesting machinery, sugarcane harvesters typically use a top-cutting mechanism to directly cut off the top of the sugarcane, harvesting only the stalks and wasting the top portion. There are several methods for harvesting sorghum: 1. Harvest the top ears separately, leaving the stalks for later processing. This method is mainly for shorter varieties where the stalks cannot be effectively utilized, resulting in low efficiency. 2. Harvest the stalks, treating the top ears as part of the stalks. This method is mainly for varieties like sweet sorghum where the top ears cannot be specifically utilized, making it difficult to maximize economic benefits. 3. Harvest the stalks and top ears simultaneously and then separate them. This method requires a complex separation mechanism, which is structurally complex, difficult to completely separate, and prone to damaging the top ears. Currently, some solutions propose using two harvesting components on the harvester to harvest the stalks and top ears simultaneously and separately. However, there are technical challenges in how to separately transport and collect the harvested stalks. The lower part of the machine is usually used as a transport channel after the stalks are harvested. However, after the top ears are harvested, the presence of the harvester's cab makes it difficult to arrange the transport mechanism. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defect that the top ear conveying mechanism is inconvenient to arrange, and to provide a conveyor for transverse conveying of top ears in a harvesting device for top ears of tall crops.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a conveyor for laterally conveying the top ears in a harvesting device for tall crops, including a conveyor frame installed behind the cutter of the harvesting device and a conveyor belt set on the conveyor frame. The conveyor frame extends along the width direction of the harvesting device and has at least two segments that are rotatably connected to each other. A folding drive device is connected between two adjacent segments to drive the segments located at the outer end of the conveyor to fold and lift upward, so as to control the conveyor to change to a flat working state or a folded state. A guide rail extending along its length direction is provided below the conveyor frame. The guide rail can cooperate with the rollers set on the harvesting device, so that the conveyor can move to the left or right side of the harvesting device according to the direction to be conveyed.

[0005] The conveyor frame includes three segments connected in sequence. The segments at both ends are rotatably connected to the two ends of the middle segment. The middle segment and the segments at both ends are connected to a folding drive device for driving the segments at both ends to fold and lift upward.

[0006] The folding drive device consists of two segmented folding arm cylinders connected to both ends.

[0007] The conveyor is provided with a drive shaft and a driven shaft at both ends to support the conveyor belt. When the conveyor frame is folded and lifted upwards in sections, the conveyor belt hangs freely on the drive shaft and the driven shaft.

[0008] The conveyor frame is provided with a blocking mechanism below it to prevent the conveyor belt from drooping downwards when it is in a segmented, upward-folded and lifted state.

[0009] The guide rail is a track groove set below the conveyor frame, and the conveyor frame is mounted on the rollers of the harvesting equipment through the track groove.

[0010] The harvesting equipment is equipped with a lateral drive device for driving the conveyor frame to move laterally on the rollers.

[0011] The lateral movement drive device is a lateral movement cylinder with its two ends connected to the harvesting equipment and the conveyor frame, respectively.

[0012] Each section of the conveyor frame is equipped with a guide rail. When the conveyor frame is in a flat working state, the guide rails of each section are connected to form a continuous guide rail.

[0013] The beneficial effects of this utility model are as follows: The conveyor adopts a segmented, foldable structure. While ensuring sufficient length to meet the top ear conveying span, it can also retract towards the center by folding and lifting the outer segments, thus saving space on both sides and improving the header's adaptability to roads and environments during non-operational conditions such as transportation. Through the cooperation of the guide rails of each segment and the rollers on the header frame, it can move laterally to the left or right of the harvester on which the header is mounted. On the one hand, it can change the conveying direction according to the position of the loading equipment to meet the needs of different operating environments. On the other hand, foldable segments can be set at both ends of the conveyor, which, while meeting the folding and retraction requirements, also extends the top ear conveying distance.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. The specific contents listed in the following embodiments are not limited to the technical features necessary to solve the technical problem described in the claims. Furthermore, the listed embodiments are merely a part of this utility model, and not all of them.

[0021] like Figure 1 As shown, the conveyor 1 of this utility model includes a conveyor frame 101 and a conveyor belt 102. The two ends of the conveyor 1 are respectively provided with a drive shaft 103 and a driven shaft 104. The drive shaft 103 and the driven shaft 104 are mounted on the conveyor frame 101. The conveyor belt 102 is supported and assembled on the conveyor frame 101 by the drive shaft 103 and the driven shaft 104.

[0022] like Figure 2 As shown, the conveyor 1 is mounted on the top ear harvesting equipment for tall crops via a conveyor frame 101, positioned behind the cutter of the harvesting equipment. The cutter is the blade used to cut the top ear in the harvesting equipment; it is mounted in front of the top ear header frame 2, which is supported by a cantilever structure, allowing it to be raised to a sufficient height to cut the top ear. The conveyor 1 is positioned behind the cutter, and the cut top ear falls onto the conveyor for transport and collection. The conveyor frame 101 extends along the width of the harvesting equipment, and its extension extends beyond the top ear header to the loading equipment (e.g., a loading vehicle) on the side of the harvesting equipment.

[0023] Conveyor 1 extends laterally to transport goods sideways, avoiding interference with the harvesting equipment's cab and facilitating its placement on the harvesting equipment. However, due to the large lateral span required for conveyor 1, and to avoid hindering the harvesting equipment's movement on the road during non-operational periods, the conveyor frame 101 of conveyor 1 is configured with at least two mutually rotatably connected segments. These rotatable connections allow the two segments to fold. A folding drive device 4, such as a hydraulic cylinder, connects adjacent segments, enabling the segment located at the outer end of the conveyor to fold and lift upwards.

[0024] exist Figure 2 and 3 In the illustrated embodiment, the conveyor frame 101 includes three segments connected in sequence. The segments at both ends are rotatably connected to the two ends of the middle segment. A folding drive device 4 is connected between the middle segment and the segments at both ends. The folding drive device 4 is in the form of a folding arm hydraulic cylinder, with its two ends connected to the middle segment and the end segment, respectively. The folding drive device 4 is used to drive the segments at both ends as follows: Figure 3 As shown, it folds and lifts upwards. This structure allows for control of the conveyor's movement. Figure 2 The flattened working state shown and Figure 3 Switch between the folded and collapsed states shown.

[0025] like Figure 3 As shown, when the conveyor frame is folded upwards in sections, the conveyor belt 102 is no longer tensioned and hangs freely over the drive shaft and driven shaft. A blocking mechanism, such as a base plate or crossbar, can be installed below the conveyor frame 101 to prevent the conveyor belt located below the frame from drooping downwards when folded upwards in sections. This method of folding the conveyor frees up space on both sides, improving its adaptability to roads and the environment during non-operational conditions.

[0026] like Figure 1 and 2 As shown, the header frame 2 is equipped with rollers 6 for supporting the conveyor frame 101. Multiple rollers 6 can be installed. The conveyor frame 101 is mounted on the rollers 6 and can move laterally along the left-right direction of the harvesting equipment. The harvesting equipment is equipped with a lateral movement drive device 5 for driving the conveyor frame 101 laterally on the rollers 6. The lateral movement drive device 5 can be a lateral movement cylinder structure, and it can be located below or to the side of the conveyor frame 101. The two ends of the lateral movement drive device 5 can be directly connected to the harvesting equipment and the conveyor frame, or they can be connected to the conveyor frame through a transmission mechanism such as a chain. The lateral movement drive device 5 enables the following movement: Figure 2 and 3 As shown, the conveyor 1 is driven to move and extend to the left or right of the harvesting equipment as needed to meet loading requirements in different directions.

[0027] Below the conveyor frame 101 is a guide rail 105 that mates with the rollers 6. The guide rail 105 can be a track groove or other similar structure, extending along the length of the conveyor frame 101. The conveyor frame is mounted on the harvesting equipment via the track groove, serving a positioning and guiding function, allowing the conveyor to move to the left or right of the harvesting equipment according to the direction of transport. For each section of the conveyor frame 101, each section is provided with a guide rail 105, and the position and size of the guide rails in each section are adapted to each other. When the conveyor frame is in a flattened state, the guide rails of each section can be connected to form a continuous guide rail, thereby increasing the range of left and right movement of the conveyor and making full use of the length of the conveyor to meet the loading needs on both sides.

[0028] The above description of specific embodiments is only for the purpose of helping to understand the technical concept and core idea of ​​this utility model. Although specific preferred embodiments have been used to describe and illustrate the technical solution, they should not be construed as limiting the utility model itself. Those skilled in the art can make various changes in form and detail without departing from the technical concept. These easily conceived changes or substitutions should all be covered within the protection scope of this utility model.
